What adaptations allow squids to be successful predators?
Two external adaptations for a squids predatory life are that it pushes ink to blind predator some have venom camouflage- (chromatophore and iridocyte) jet propulsion.
What kind of biome does a colossal squid live in?
The colossal squid lives in the ocean biome. These squid can be found in the deep ocean, but may also come in closer to shore.
How does the blue ringed octopus defend itself against other animals?
It sprays poison out and distracts the moray eel by covering the eyesite, and waisting its time. Then, the moray eel sucks up the poison, and the blue ringed octopus comes to attack the moray eel, and poison the body.
To understand why octopus blood is blue, we need to first understand why our blood is red. The blood of most vertebrates (animals containing a backbone..ie: Humans, dogs, birds, reptiles, etc...) is red because our blood contains a protein called hemoglobin. Hemoglobin is the molecule responsible for carrying oxygen. Hemoglobin is located in red blood cells. When red blood cells enter the lungs, hemoglobin binds oxygen molecules, and as the red blood cells flow throughout our bodies, hemoglobin releases the oxygen to our cells, nourishing them. The way that this is done is through the use of Iron. Iron (specifically Iron III) is an ideal molecule for binding oxygen. When iron binds oxygen it turns RED. This is why our blood is red; because the hemoglobin within our red blood cells contains iron, which turns red when bound to oxygen. When hemoglobin is not bound to oxygen, our blood is blue as well. Go ahead, look at one of your veins. Veins carry oxygen-depleted blood back to the lungs and heart. Until this blood contacts more oxygen, it remains blue. Now to answer the question: why is octopus blood blue? In short, Octopus blood lacks hemoglobin, and hence lacks iron. Oxygen transfer is accomplished by another (less efficient) protein known as hemocyanin. This protein, as well as other molecules in the octopus' blood give it the characteristic blue color.
The tree octopus is a fictional creature.
The "Pacific tree octopus" (pseudo-classification Octopus paxarboria) was a 1998 internet hoax that was intended as a parody of actual ecological awareness groups. Occasionally individuals will mistake the site as one promoting the preservation of an actual animal. A small following has provided fake photos, testimonials, and other material.
Yes, Squids do eat sea snails. Squids hold them with there legs and eat them.
and Im french and there not IDIOTS
What is the symbiosis relationship between moray eels and cleaner shrimp?
According to a rumourus fact, it suggests that cleaner shrimp clean the teeth of eeks. Though this may be mistaken and false
Does a squid have a special adaptation?
Squid have very good eyesight and may even be able to see in color. The squids' two tentacles are specially adapted for feeding and they use them to grab their prey. Squids can swim very fast by its 10 arms. Squid have some unique adaptations. Some can change color, some use to create light, and some shoot ink to cloud the water and lose predators.
What is the symmetry of a lugworm bilateral or radial?
Eels are fish, so, like all vertebrates, have bilateral symmetry. This means they have symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side.
What is the size of a giant squid?
About 75-100 feet long. Their eyeballs alone are as big as school bus wheels!
In what two ways do planarian show cephalization?
Yes, they have (primitive) sense organs anteriorally placed - this represents cephalisation, as does the aggregation of nervous tissue to monitor and respond to impulses from the anterior sense cells/organs.
How are jellyfish and squids alike?
Jellyfish are actually closely related to the Hydra. The greatest similarity between the two is that they both have a type of nervous system called a nerve net.
Copepods are animals, they feed and reproduce. They are small arthropods. Some species are parasites and will dig into fish and feed on their body fluids, some attach onto the eyes of sharks such as the Greenland shark, and most float through the water eating food particles.
What type of fish do squid eat?
fish
It depends on the size of the squid, they are capable of eating shrimp to something as big as they are..so a varied diet !
What is a squid's shell called?
at the bottom of the ocean
-- You can find squid most anywhere, including the shallows, depending on the species. --
What is the weight of a vampire squid?
I suppose you mean "How much does a vampire squid weigh"? If that is indeed what you meant, Vampire Squid can grow up to about 1 foot long along and generally weigh about (insert weight here because I really don't know) Sorry bro. I researched for about 30 minutes and came up blank
The function of suction cup of squid?
As far as I know, they're used for self-defense and to hold onto food while they're eating it. The suction cups are lined with razor sharp "teeth" which can leave pretty nasty scars on a while looking for a squid snack. I hope this helps you! :D
What would a squid be classified as?

How many giant squid do sperm whale eat a day?
Sperm Whales are carnivores and feed on several species. The most notable prey species are the giant squid, the colossal squid, octopuses, and diverse fish like demersal rays, but the main part of their diet consists of medium-sized squid. Due to their sheer size, some prey may be taken incidentally while eating other items.
Does a baby squid come out alive or in a egg?
Squids lay about 200.000 eggs each time.
This depends on the specimen though.
